Jansen didn’t give an official statement on her pregnancy, but mainman Tuomas Holopainen told TeamRock: “The issue of Floor having a kid came up earlier this year. I asked her if she had been thinking about having a child and she said, ‘Yeah, actually, I have.’

“So I said, ‘Well, we’re thinking of having a break so if you want to…’ And here we are.

“It’s just a wonderful, beautiful thing because now she gets to be with him or her for a year before we continue so it’s perfect timing.”

Jansen, whose partner is Sabaton drummer Hannes Van Dahl, has worked with Nightwish since 2012 and was announced as the band’s full-time singer in 2013. She replaced Anette Olzon on what was initially seen as a temporary basis before being given the role permanently.
